Background: Surgery represents the only curative treatment for stage I-III midgut neuroendocrine tumors (NETs). At present, there are very limited data on the risk of postoperative recurrence. The optimal modality, duration and frequency of surveillance have not been well established. In this work, we investigated the long-term risk of recurrence, peak timing of recurrence, and potential predictors of relapse in patients with stage I-III midgut NETs. Methods: We retrospectively evaluated 129 patients with stage I-III midgut NETs who were seen at the Moffitt Cancer Center between 2000 and 2010 following an R0/R1 resection...

INTRODUCTION: Silent metastatic gastric adenocarcinoma presenting as appendicitis is very rare. Rare pathologies may be encountered during common operations such as appendicectomy and an awareness of possible alternative pathological entities would be helpful in a surgeon's wealth of knowledge. PRESENTATION OF CASE: A 63-year-old man presented with a three-day history of acute abdominal pain suggestive of appendicitis. Intra-operatively, a macroscopically inflamed and perforated appendix was found...

Examination of >12 lymph nodes (LNs) is important for the diagnostic accuracy of nodal status following resection of colorectal cancer. In the present study, the efficacy of a fat dissolution technique for LN retrieval was evaluated using resected colon and rectum mesentery. First, the resected mesentery was searched for LNs by inspection and palpation immediately after surgery. Subsequently, fat dissolution liquid was applied to the remnant fat and the LN search was repeated. The primary endpoint was whether the second assessment would increase the number of evaluated LNs...

The patient was 69-year-old man. For the remnant gastric cancer, partial resection of the remnant stomach with combined resection of mesentery of transverse colon was performed. Pathological diagnosis was adenocarcinoma(tub2>tub1), M, B- 50-AJ, type 3, pT4b(mesentery of transverse colon), pN0, CY0. A CT scan of 6 months after the surgery showed a tumor on the left side abdomen and diagnosed as peritoneal recurrence. Chemotherapy consisted of 1 course of TS-1(100mg/body) plus cisplatin(70mg/body), 4 courses(2 weeks administration and 1 week break)of TS-1(100mg/body), 8 courses of docetaxel(80mg/body)...

We report a case of the pancreas head cancer with peritoneal metastasis, which was resected curatively after chemotherapy. A6 6-year-old male was referred to our hospital for the treatment of biliary stenosis. The serum CA19-9 level was elevated and abdominal CT scan showed stenosis of distal bile duct. By laparotomy, we noticed mass in the head of the pancreas with 8mm of the seeding nodule in a diameter at jejunal mesentery which was diagnosed as adenocarcinoma by intraoperative frozen sections. Therefore, the patient was diagnosed as pancreas head cancer with peritoneal metastasis...

BACKGROUND: Advanced epithelial ovarian cancer (EOC) often involves the peritoneum. Because complete resection of tumor and carcinosis is the most important prognostic factor, the peritoneal carcinosis index (PCI) has been evaluated in EOC. We hypothesize that specific PCI regions comprising the small intestine with mesentery (regions 9-12) and the hepatoduodenal ligament (region 2) are more predictive of complete resection (R = 0) and survival than the entire PCI. MATERIALS AND METHODS: We analyzed prospectively collected nationwide data from 507 patients with International Federation of Gynecology and Obstetrics stage IIIB to IVB EOC who underwent primary surgery with complete cytoreductive intent...

Therapeutic proteins can facilitate the targeting and treatment of lymphatic diseases (such as cancer metastases, infections and inflammatory diseases) since they are cleared via the lymphatics following interstitial (SC or IM) administration. However, therapeutic proteins are often administered intravenously (IV). Recently therapeutic proteins have been found to access the thoracic lymph in surprisingly high quantities after IV administration. The aim of this study was to determine, for the first time, the major sites of thoracic lymph access of therapeutic proteins, and the protein properties that enhance lymph access, after IV administration...

We compared the prevalence of a baseline diagnosis of cancer in patients with and without misty mesentery (MM) and determined its association with the development of a new cancer. This was a retrospective, HIPAA-compliant, IRB-approved case-control study of 148 cases and 4:1 age- and gender-matched controls. Statistical tests included chi-square, t-test, hazard models, and C-statistic. Patients with MM were less likely to have cancer at baseline (RR=0.74, p=0.003), but more likely to develop a new malignancy on follow-up (RR=2...

Mesenteric masses are infrequent lesions ranging from benign cysts to aggressive malignancies and often present a diagnostic and therapeutic challenge. The mesentery is a frequent recipient of metastases from the gastrointestinal tract, pancreas, and biliary cancers. Primary mesenteric tumors are relatively rare, mostly mesenchymal in origin and benign in nature. Examples include gastrointestinal stromal tumors and smooth muscle tumors. We describe a 50-year-old woman, who presented with a lump in the left hypochondrium along with altered bowel habits of 2 years' duration...

BACKGROUND: Complete macroscopic cytoreduction in patients with peritoneal carcinomatosis (PC) is the basic requirement for long-term survival. Diagnostic laparoscopy (DL) can be difficult and of limited clinical value secondary to postoperative or tumor-induced adhesions. The aim of this study was to evaluate the role of DL in patients with prior surgery and PC. METHODS: The database of the surgical department of the University Medical Center of Regensburg was reviewed (9/2010-10/2014) selecting for DL in patients with PC...

Pneumatosis intestinalis (PI) is a relatively rare disease. A 70-year-old man with stage II squamous cell carcinoma of the middle thoracic esophagus was administered cisplatin plus 5-fluorouracil (CF) therapy as neoadjuvant chemotherapy. On Day 14 of the first course of CF therapy, he complained of acute abdominal pain. Computed tomography (CT) revealed PI of the entire colon and a small air bubble in the mesentery. A colonoscopy revealed that there was no finding suggestive of ischemia. Because there was no sign of peritoneal irritation, conservative treatment was selected...

The laparoscopic surgery for gastrointestinal cancer developed slowly and was at a crossroad of choice at the beginning of the 21st century. However, the team of laparoscopic surgery in Nanfang Hospital was keenly conscious that minimally invasive surgery (MIS) would bring new era to the treatment of gastrointestinal cancer. Therefore, our team went into the exploration of laparoscopic surgery for gastrointestinal cancer: (1) researching a series of anatomical theories for MIS; (2) lucubrating the applicable pattern of fascia and mesentery under laparoscopic view; (3) finding out the precise anatomical landmarks and surgical layers; (4) optimizing the operative strategy...

Mechanism-inspired drug repurposing that augments standard treatments offers a cost-effective and rapid route toward addressing the burgeoning problem of plateauing of effective therapeutics for drug-resistant micrometastases. We show that the antibiotic minocycline, by its ability to minimize DNA repair via reduced expression of tyrosyl-DNA phosphodiesterase-1 (Tdp1), removes a key process attenuating the efficacy of irinotecan, a frequently used chemotherapeutic against metastatic disease. Moreover, minocycline and irinotecan cooperatively mitigate each other's undesired cytokine inductions of VEGF and IL8, respectively, thereby reinforcing the benefits of each modality...
